You can get the mount path from the admin portal.
system---storage---select a storage domain---In the general tab page, 
you can have the nfs export path.

supo...@logicworks.pt:
well, I run the virt-v2v from the engine server, if I do a showmount 
-e it will show me the iso domain. The NFS/export storage is located 
at a NAS on the LAN, so I think I need the path to that NAS, how can I 
found it?

Hi,

Im trying to migrate a VM from a qemu kvm server. I'm not sure of the 
correct syntax:


virt-v2v -ic qemu+ssh://root@/server_ip_addr//system -op 
/export_domain/ --bridge ovirtmgmt /kvm_vm_name/


I have setup a NFS/export storage on the manager, for the export

Re: [Users] Lun snapshots by a san

2013-04-17 Thread Shu Ming

pierre Labanowski:

Hello everybody,

I have a question, or more precisely information or best practice.

I use oVirt 3.1 with an attachment on fiber channel on my SAN. Makes it
even the San snapshots that are replicated on a remote site.

it's a procedure for adding a new Storage Domain to another Data
Centers (oVirt) in order to recover the state of a VM snapshoted by the SAN?


If I understand correctly, the remote SAN of you can snapshot the 
storage domain(physical lun in the SAN) lively. And you hope to recover 
the storage domain with the previous snapshot stored in the SAN.
So you create a new storage domain for another data center and restart 
the VM from the newstorage domain. I am not sure if the VM disks in the 
storage domain snapshot is in consistent date if the SAN snapshot the VM 
in a running state. I think the VM OS should be notified and make sure 
it is in consistent state before the SAN can do the snapshot, also the 
VM OS should be notified with the finish of the snapshotting..


I've read the documentation on Disaster Recovery but it's for the
site-to-site failover (i don't have dual architecture of ovirt) while my
demand here is for the state recovered a current domain. And only to
export the VM(snapshoted by a san) for restore in the current storage
(production).

thank you
Pierre

oVirt project was initiated from virtual desktop project. It supported 
an open desktop protocol SPICE from the beginning which gave a nice 2D 
performance driven by the various graphics drivers on different OSs. Do 
you have a target in mind? Like what is ratio of virtual desktops per 
physical servers? Does the virtual desktop support support video 
playback? Do you need to support other client protocol besides SPICE?

Re: [Users] SPM is always contending - resolved

2013-04-06 Thread Shu Ming

Which type of storage domain was in your engine? NFS? iSCSI? or other types?
Andy Singleton:

Problem resolved.

The clue was obviously in the engine.log (FSCK error) but I couldn't 
see what was needing an fsck or why this would prevent the storage of 
every vm from being mounted.

I still dont understand the whole of the ovirt storage mechanism.

More information was in the node vdsm.log - It pointed here. 
/dev/mapper/9ed5a2fe--ae4c--433f--a15f--2c710ed5156f-master


One fsck later problem resolved.

Re: [Users] way to edit iSCSI storage domain?

2013-04-03 Thread Shu Ming

Yuriy Demchenko:

I guess you misunderstood me
I'm going to try this scheme:
   |STORAGE|
FC /   \
|SERV1/tgtd||SERV2/tgtd|
iSCSI   \  /
 |ethernet switches|
iSCSI
   |blades|blades|blades|


I am still confused if SERV1/SERV2 are used as a iSCSI bridge to the 
storage only or used as VDSM host also?  If they are used as VDSM host 
and both of them can have FC channel to the storage, why not create FC 
storage domain for them instead of iSCSI domain?




serv1/serv2 - connectivity isnt a problem, multipathed FC scheme, all 
good. Same lun accessible for both servers and than exported via tgtd 
to iSCSI: with different target names (iqn.2013-03.serv1:store, 
iqn.2013-03.serv2:store), but same vendor_id, product_id, scsi_sn, 
scsi_id. That way client can login into both targets and see lun as 
multipathed device.
And multipath failover scheme (via custom config with 
path_grouping_policy=failover for corresponding vendor_id/product_id) 
is on blades-clients - so they use only one target at time (no 
round-robin or similar stuff), but with ability to switch to another 
target in case one of serv1/serv2 is down.


However, in my case serv2 would not be available during oVirt setup 
(need to setup ovirt and virtual servers to move stuff first), so i 
cant enter both targets on storage domain initialization - that's why 
I'm asking if there's any way to edit storage domain details after 
initialization without destroying it (maybe directly via sql or 
something).

Re: [Users] way to edit iSCSI storage domain?

2013-04-02 Thread Shu Ming

Yuriy Demchenko:

Hi,

is there any way to edit iSCSI storage domain: change/add targets ? 
(lun, id, sn and actual content wouldn't be affected) Without VM 
export/import process - downtime should be as little as possible.


I'm researching possibility to use oVirt in env where I have only FC 
storage, connected to 2 servers (and sadly, second server will be 
available later, hence my question about changing targets in oVirt) 
and bunch of blades, on which i would like to run virtualization (no 
fc storage connectivity) - so idea is to share storage via iSCSI/tgtd 
and use multipathd with failover mode to protect from storage 
I am not sure if the multipathd can recognize the FC path to the storage 
when the second server is available and regards it as the same as the 
iSCSI path used before. If it is not, I think the device under 
/dev/mapper may change when you cut the iSCSI path off and then enable

Re: [Users] High Availability

2013-03-17 Thread Shu Ming

Tim Hildred:

If one host is down because of network interrupt or power
failure, the engine should know how many HA VMs are down and find
out the VM images on the storage domain to start the VM instances on
another host in the cluster. Why do we need power manager to be
configured?

Power management allows the Manager to start highly available virtual machines 
on new hosts without worrying that virtual machine hard disk images will be 
corrupted.

Imagine a situation in which the Manager cannot communicate with the host a 
highly available virtual machine is running on. If the host is still running as 
expected, and the virtual machine is also still running, the virtual machine is 
writing to its hard disk image.

Tim,

Thanks for clarification. That is what I expected.



If the Manager starts that virtual machine on another host in the cluster, then 
both virtual machine instances will try and write to the disk image, and cause 
hard disk corruption.

Power management lets the Manager be sure that only one instance of the highly 
available virtual machine is running, because the instance on the host the 
Manager couldn't communicate cannot survive a host reboot.

Tim,

Thanks for your information. I am not sure why we need power
management to be configured for the hosts running HA virtual
machines.  We only need a method to check the VM or host status and
a method to restart the VM instances with existing VM images on
another host. Is it required to force powering down the failing host
forever to make sure the failing host will not come back to live
again?




 *
Power management must be configured for the hosts running the highly
available virtual machines.
 *
The host running the highly available virtual machine must be part of
a cluster which has other available hosts.
 *
The destination host must be running.
 *
The source and destination host must have access to the data domain
on which the virtual machine resides.
 *
The source and destination host must have access to the same virtual
networks and VLANs.
 *
There must be enough CPUs on the destination host that are not in use
to support the virtual machine's requirements.
 *
There must be enough RAM on the destination host that is not in use
to support the virtual machine's requirements.

I think that there is some confusion here so I will explain what are
the
configurations for fail-over.

power management will reboot your host if a connectivity issue is
detected so all your vm's will be killed.
resilience policy will allow you to choose vm migration policy during
a
host failure and its configured in the cluster level (clusters -
select
cluster - general sub tab - edit policy)
High Availability is configured only for servers type vm's and what
it
does is re-run the vm in case the pid of the vm is killed (so most
commonly, if you have power management configured, and the host is
rebooted, the vm will start automatically on a different host).

so it really depends what you want. if you want vm migration than
look
into cluster policy, if you want a specific vm to always be up and
you
don't care about the other vm's than configure power management and a
HA
vm. it really depends on what you need.

the size should be updated by queries that are sent to vdsm on domains

I think vdsm domains do have their own meta-data except the lvm or posix

If you want to be extra careful you can always put the export domain in
maintenance before the extend :)
If the export domain come back to life, I think the domain meta data 
should be invalidated after the extend.

So you have a block device in NFS server to be extended from 200 to 
50GB?I think you should extend both the block device and the file 
system on the block device in the server side.   To oVirt,  it doesn't 
save the size in storage domain' meta-data and I believe the size is 
only stored in the engine server.  The only issue is before the engine 
refresh its metadata in the next time, there is a window with the 
meta-data out of sync.   Please let us know if it is successful.

Google translate suggests that your question relates to an 
installation issue - you installed oVirt 3.2, ran engine-setup, 
selected a POSIX FS type data center, and do not see any storage 
domain. However, the Gluster volume is visible in the node view. Is

Have you had any issues using the Gluster volume outside oVirt?

I hope someone can help you with your query!

Google translate suggests that your question relates to an 
installation issue - you installed oVirt 3.2, ran engine-setup, 
selected a POSIX FS type data center, and do not see any storage 
domain. However, the Gluster volume is visible in the node view. Is 
that correct?


Have you had any issues using the Gluster volume outside oVirt?

I hope someone can help you with your query!

Thanks,
Dave.

选择posix compliant fs之后,增加glusterfs的volume在WEB UI上提示不成功,
但是在node上使用gluster volume info查看已成功创建。
请问一下这个问题如果解决。

Re: [Users] Ovirt + Spice + VDI

2013-03-05 Thread Shu Ming

Mohsen Saeedi:

Hi
I want to know, we are force to install one windows per user? does 
spice can provide a multi remote connection to a single windows XP 
machine?
I want to install one windows XP as virtual desktop and then share it 
with more than one users.is it possible in now or in the futures?
I think you are talking about mutiple sessions in one windows desktop 
servers.I believe you must use RDP protocol to access those 
sessions.  Spice is for one window desktop per user.

iirc, it's a checkbox in the user portal to pass the wan option flag 
to spice.


Does this checkbox mean there are some optimization for spice on wan? 
How does the checkbox affect the remote video stream support? It seems 
that spice protocol waste many cycles on mjpeg encoding and decoding for 
video stream.

Re: [Users] snapshot taken while live VM operates cause unresponsive hypervisor behavior

The libvirt and qemu version in the VDSM host may help the debugging.
Alexandru Vladulescu:


Hi,


Using 3.1.0-3.19 from dreyou's repo on Centos 6.3 version, running 
multiple VM on the hypervisor node and attempting to take a snapshot 
from one of the running VMs generates errors for VDSM daemon as show 
below:

Paste from ovirt admin GUI log:

Looking through htop command could see that VM were still running and 
responsive but any vdsclient command failed with the upper code paste 
I have given. Solution here was to connect to each VM, shut it down 
and restart vdsmd and power it up again. There's no problem with the 
storage size as it has aprox 800GB free of space and running through 
NFS. All nfs mount points were running okay at that time.


After the VM has been snapshoot-ed went into pause mode and had to 
un-pause it from GUI, but the VM was still responsive through network 
and operations.


Has anybody seen something related to this by now or it's just related 
to 3.1 version ? Mentioning the fact that I did a research on the 
similar mailing list topics and could not find something related to 
this error. I would happily provide logs if needed.

Alex

Bug was filed here.

It seems that it is a openjdk bug.
https://community.jboss.org/message/796347?_sscc=t#796347
Jonathan Archer:

Hi All,

Just wondering if anyone could shed some light on an issue I'm seeing?

I've followed the instructions on the wiki to try and get an ovirt 
setup running. (F17 minimal, updated, add repo, yum install 
ovirt-engine, engine-setup)
All that seemed to go OK, and the database creation etc seemed to be 
fine, however starting the ovirt-engine service seems to have failed 
to start, was getting a http 503 error on trying the web interface.


Looking deeper into it, it seems that jboss-as seems to be failing to 
start with some errors around logging.
when I run systemctl start ovirt-engine.service i get the following in 
the logs:
Feb 6 14:33:52 host1 engine-service.py[25212]: Started engine process

Re: [Users] VM migrations failing

2013-01-30 Thread Shu Ming

Hi,

Just curiously,  did you install  oVirt packages from 
http://resources.ovirt.org/releases/nightly/rpm/EL/6/noarch/  ?

And there is no stable oVirt release 3.1/3.2 for RHEL.

Dead Horse:

The nodes are EL6.3 based.

Currently installed libvirt packages:

libvirt-lock-sanlock-0.9.10-21.el6_3.8.x86_64
libvirt-cim-0.6.1-3.el6.x86_64
libvirt-0.9.10-21.el6_3.8.x86_64
libvirt-python-0.9.10-21.el6_3.8.x86_64
libvirt-client-0.9.10-21.el6_3.8.x86_64

and qemu packages:
qemu-kvm-0.12.1.2-2.295.el6_3.10.x86_64
qemu-kvm-tools-0.12.1.2-2.295.el6_3.10.x86_64
qemu-img-0.12.1.2-2.295.el6_3.10.x86_64

Thus my presumption here given the above is that 
virDomainMigrateToURI2 has not yet been patched and/or back-ported 
into the EL6.x libvirt/qemu?


virDomainMigrateToURI2() is supported in libvirt-0.9.10, I am not sure 
if qemu-kvm-0.12.1.2 supports it.

/var/log/libvirtd.log may help to verify this assumption

Re: [Users] Installing a lab setup from scratch using F18

2013-01-21 Thread Shu Ming

2013-1-22 2:11, Joop:
As promised on IRC (jvandewege) I'll post my findings of setting up an 
ovirt lab environment from scratch using F18.

First some background:
- 2 hosts for testing storage cluster with replicated gluster data and 
iso domains (HP ML110 G5)

gluster data or cluster data?


- 2 hosts for VMs (HP DL360 G5?)
- 1 managment server (HP ML110 G5)
All physical servers have atleast 1Gb connection and they also have 2 
10Gb ethernet ports connected to two Arista switches.
Complete setup (except for the managment srv) is redundant. Using 
F18-x64 DVD and using minimal server with extra tools, after install 
the ovirt.repo and the beta gluster repo is activated.

This serves as a proof of concept for a bigger setup.

Problems sofar:
- looks like F18 uses a different path to access video since using the 
defaults leads to garbled video, need to use nomodeset as a kernel option
Do you mean the VDSM host installed with F18 or the guest in the host 
with FC 18 here? I suppose you don't have much chance to access the 
graphics screen of the VDSM host.


- upgrading the minimal install (yum upgrade) gives me 
kernel-3.7.2-204 and the boot process halts with soft locks on 
different cpus, reverting to 3.6.10-4.fc18.x86_64 fixes that. 
Managment is using 3.7.2 kernel without problems BUT it doesn't use 
libvirt/qemu-kvm/vdsm, my guess its related.
- need to disable NetworkManager and enable network (and ifcfg-xxx) to 
get network going
- adding the storage hosts from de webui works but after reboot vdsm 
is not starting, reason seems to be that network isn't initialised 
until after all interfaces are done with their dhcp requests. There 
are 4 interfaces which use dhcp, setting those to bootprotocol=none 
seems the help.
Usually, I use the static IP for each server because the engine add the 
VDSM host by IPs.


- during deploy their is a warning about 'cannot set tuned profile', 
seems harmless but hadn't seen that one until now.
- the deployment script discovers during deployment that the ID of the 
second storage server is identical to the first one and abort the 
deployment (Blame HP!) shouldn't it generate a unique one using uuidgen??



Things that are OK sofar:
- ovirt-engine setup (no problems with postgresql)
- creating/activating gluster volumes (no more deadlocks)

Adding virt hosts has to wait til tomorrow, got problems getting the 
dvd iso onto an usb stick, will probably burn a DVD to keep going.

Re: [Users] Configure NFS resource from Host

2013-01-09 Thread Shu Ming

jj197005:

Hello everybody,

I'm trying to configure and install oVirt for test in our University 
faculty. I have installed an engine an a host, both of them with 
Fedora 17. The engine is working and I can log-in in the Data Center 
with admin user. I have tried to add my host to the data center portal 
and I successfully done. After that I have tried to add a NFS resource 
which is in the host that I have added. If I open a console in the 
engine and log-in as vdsm user, I can mount the NFS resource without 
problems. The problem is when I tried to add this NFS resource to the 
Data Center.


Have you tryied to open an console in the host and tried the same 
command in the host as in the engine?




I have followed the tutorial 
http://www.ovirt.org/Quick_Start_Guide#Configure_Storage, but when I 
have completed the form and pressed Ok, after one or two minutes I 
receive one screen with bellow error:


Error: A Request to the Server failed with the following Status Code: 
500


I'm attaching the vdsm.log file with the lines that are created with 
this operation. I hope that someone can show me what is the problem. 
If you need more information aboout the installation I can show it.


Many thanks in avanced,

Juanjo.

Re: [Users] Storage domain mount options

2013-01-08 Thread Shu Ming

Alexandru Vladulescu:


Hello Guys,


I would like to ask you help for the following problem I am facing 
right now.


As we know, on the Storage tab we can configure storage domains in 
many types. I am using NFS, and when configuring a such export on the 
Advanced Parameters section we can only adjust the NFS version, 
Retrans and Timeout.


After a successful configuration setup, on all hypervisors I have the 
mount share declared attached. The result of mount for the share 
datastore looks like below:


nas01.net:/datastore01/nas01.ISO on 
/rhev/data-center/mnt/nas01.net:_datastore01_nas01.ISO type nfs 
(rw,soft,nosharecache,timeo=10,retrans=6,vers=4,addr=10.20.30.10,clientaddr=10.20.30.102)


All good and sound but how can I tune the NFS mounting command, for 
example let's say adding noatime value to the mount option list ?

New domain --- Advanced Parameters.






Many thanks,
Alex.

Re: [Users] Storage domain mount options

2013-01-08 Thread Shu Ming

Alexandru Vladulescu :


Dear Shu,


Exactly what I was saying, in that section we can only change in the 
Advanced Parameters the NFS version, the Retransmissions and the Timeout.
Sorry, was not seeing these. I am afraid you can not append other 
options, for neither ovirt engine nor VDSM accepts other options than 
Retransmissions and the Timeout.




Therefore I see exactly no field for additional mount options.

As I know there is a thread on the mailing list about the new features 
that should be included in the 3.2 version release. I think would be 
useful to include this one too to the GUI, but again my question, how 
could this be modified in the stable 3.1 release ?

 Hi,

 So, Finally I reinstalled the whole cluster after I have exported
 every VM.

 I followed this wiki
 http://wiki.dreyou.org/dokuwiki/doku.php?id=ovirt_rpm_start31.

 Everything went up except that I just have one host installed in the
 cluster. The other host is still serving the old cluster

 When trying to import my old VMs I got problems with some of
them not
 beeing imported. But 3 of my VMs did and one of them was my
 mailserver... but when I try to start the VM I hit the wall again.

 I have attached the vdsm.log, right now I cant see the forest

Re: [Users] What do you want to see in oVirt next?

2013-01-04 Thread Shu Ming
1) I would like to have the ability to import an existing VM image from 
outside as a template into oVirt, then new VMs can be cloned from this 
template.
2) I would like to have an oVirt trial package based on nested-kvm. This 
package will contain several vdsm node images, one engine image and one 
storage several image. After the package is installed into a physical 
server, the images can be started as VMs including the engine, the VDSM 
nodes, the storage server. The VDSM nodes must support nested-kvm to 
have nested VM on them. It is very quick and simple for a new-comer to 
try the oVirt envionment.

Hi Everyone,

Re: [Users] VM has paused due to unknown storage error

2012-12-03 Thread Shu Ming

David Wilson:

Hi everyone,

Some feedbackon this error, and a question I hope that someone could 
possibly assist with.
I managed to get the guest running again byusing dd and qemu-img to 
export the filesystem image and base image, convert to raw format and 
run a fsck on the looped partition.
I am happy you make that work.   Can you describe more details about how 
you dd the guest image? And how did you use qemu-img to export the 
filesystem image and base image.



When mounted as a loop filesystem, fsck easily repaired it.

Any ideas why oVirt kept pausing the guest and did not allow fsck to 
repair the filesystem?

Hi everyone,

Sunday fun :)

One of our critical Linux VMs ran out of disk space. I cleared up 
space by removing old application logs within the guest, rebooted the 
guest and was presented with the following information message during 
bootup when the filesystem ext3/4 scan runs:

/Clearing orhpaned inode ./
Shortly after this message the the guest is paused by oVirt and the 
VM has paused due to unknown storage error message is displayed in 
the oVirt web GUI.


On the physical node itself, I found the following error

Any ideas on how to get more informationon what exactly the error is?

I've tried booting the guest into rescue mode, run a manual fsck on 
the logical volume but each time the guest is automaticall paused due 
to the unknown storage error.


We are using a FC SAN for storage, sowhat I've decided to try is 
export the disk using dd on the physical node and then try 
repairing it by mounting it as a loop filesystem on another physical 
server, and then use dd to import it back in again.


Is this the right approach to take to get the system back online?

2012-10-21 Thread Shu Ming


2012Jorick Astrego:

Dear all,

After some problems I have my ovirt setup running now. But I run into 
a new problem with the network configuration.


We have a quad nic with 4 gigabit connections over 2 switches (2X2) 
and an active/passive iscsi SAN. The first is connected to switch 1 
and the second to switch 2 with a 10Gbe link.


Do you mean you have a host(ovirt node) with a quad nics conneting to 
switches? And one SAN connecting to the switch 1 in another side, the 
other SAN conecting to switch 2 with a 10Gbe lnk?

I think a picture will make the text description more comprehensive.




Now I would like to use iSCSI multipathing instead of bonding but I 
cannot use the same vlan for multiple storage networks and I cannot 
assign the same storage network to several nic's.


I could use bonding, but we use 4 links over 2 switches and if I read 
everything correctly bonding only works through a single switch.


How do other people achieve this?

Oh, does this take advantage of host swap space as well?  I
thought I had read oVirt could do that somewhere, but I have been
reading about so many different virtualization systems over the
last few months that when the RHEV 3.1 Admin Guide

https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Virtualization/3.1-Beta/html-single/Administration_Guide/index.html
did not mention swap space in section 4.2.2.2. Memory
Optimization Settings Explained, I was not sure if it applied
here.  This is all it says at the moment:

Memory page sharing allows virtual machines to use up to 200%
of their allocated memory by utilizing unused memory in other
virtual machines. This process is based on the assumption that
the virtual machines in your Red Hat Enterprise Virtualization
environment will not all be running at full capacity at the
same time, allowing unused memory to be temporarily allocated
to a particular virtual machine.


Do you have a reference handy that confirms and explains this?  I
put some speedy SSDs in my hosts to hopefully take advantage of
this (and maybe run gluster), so I am hoping to see that in print
somewhere.  I'll dig it up if you don't have it handy, but a
confirmation that this is your experience and understanding would
make me feel better in the mean time.


let me explain my (now fixed) problem i have a ovirt host with 8 GB 
Ram and 12 VMs every with 256 MB Physical Memory Guarantee. When i 
start my two mysql-cluster vms they will use the 256 PMG plus 3,75 GB 
MS they have defined a max of 4 GB MS. At this poitn now the problem 
begins the mysql taken the hole memory in both vms and now there is no 
more free ram at the host and it is not possible to start more vms.


In my understanding, you need to hard cap the physical memory used by 
the cluster VM.  That will  make sure all of the physical memory used by 
the VM will not exceed the cap, say 2G.  In total,  the two cluster VMs 
will use 4G memory at  most, then the host will have 4G memory at least 
to start other VMs.  Is that what you want?





(this is also speculation im not a expert) So i need for my 
understanding a higher rate of memory overcommit to be able to start 
all vms, and for that the host must use the swap to have enough memory 
for overcomit to start all vms and yes the higher the rate, the worse 
the performance. I'm not sure if this is the right or good way tho fix 
this problem


(sorry for my bad english I hope this is understandable)

Re: [Users] Hot Snapshotting of virtual disks

2012-10-17 Thread Shu Ming
Basically, backup is different from snapshotting. Backup should have 
another storage different from the current share storage to store the 
disk content. oVirt 3.1 does have support for live snapshot of the VM 
disks and Qemu 1.1 is required at least to support this operation. In 
oVirt 3.1, you can also create an backup domain to store the VM disks, 
but I think it is not the real backup to another physical storage. So 
you may have to copy the snapshot made to other physical storage manually .


2012-10-18 9:20, Jason Lawer:

Hi,

Can anyone give advice on what they are using for backup on their ovirt 
deployments. We have been using tar balls  rsync on our linux servers, but are 
looking for something more manageable and the number of servers grows rapidly.

I ask because I have been looking at a few options. The first idea that came to 
mind was a hot snapshot of the virtual disk, however from what I can see ovirt 
won't allow that. Most of the others have serious drawbacks, so I wanted to 
know if anyone had a silver bullet before I put more time into it.

Re: [Users] Is this dd operation harmful?

After reading the code, every mailbox should be 4096 byte size.
And the total mailbox size is host * 4096. Ony one host is here, so
the total mailbox size here is 4096. why should the 'dd' operation
read 1024000 byte which is 1000K byte much lager than 4096 here?

That's storage.storage_mailbox.SPM_MailMonitor, polling for lvextend
requests. dd is used, since in the old days, vdsm did not have
storage.fileUtils.DirectFile.

The behavior is expected, but I cannot say that it is harmless.
The mailbox should be high on

   The idea is to import a VMWare (vmdk) o Xen (ova) virtual hdd on oVirt.

As far as i remember, there is no way to import just a disk,
only vm/template.
i guess you could find a way to create an OVF to represent a vm that 
attached to that disk,

import it and then detach the disk from the fake vm


Do we have such a tool in oVirt? Or just create the OVF file manually?  
After I get the OVF file,  where should I put the OVF file and the disk 
file to be imported?

this would work - just create the VM on an NFS storage domain
with a disk
the same size as origin, and copy over the disk you had.
a bit trickier for iscsi, so i'd do this with nfs.


Thanks
- Trey




Why is it trickier with iSCSI?  Currently the only Data Center I
have
functioning in oVirt only has iSCSI storage available.


with iscsi, you will have to create the disks as pre-allocated,
and use DD
to overwrite them.
NFS doesn't have to be pre-allocated.
and since you are using pre-allocated, you need to use the RAW
format iirc



Currently most of my KVM VMs are qcow2, so converting them to raw
would not be a problem.  However, why is DD necessary?  Why can't I
overwrite the image_name.img with my *.img file ?  Since I've
used
mostly qcow2 in my time with KVM/libvirt I may lack some
understanding
of how to correctly handle raw images.

in both cases there aren't any .img files.
you can convert you qcow2 to raw before copying them over to iscsi or
nfs using qemu-img convert.
it is not necessary, but will save you failing on small details
between
the two.
using the export domain is safest, even though it doubles the amount
of IO


Would a qcow2 image with preallocation=metadata be possible on an
iSCSI data store?

ayal?


nope.  metadata preallocation means that each logical block has a corresponding 
physical block.
Ayal, by saying logical block and physical block here,  what do they 
stand for in linux systems?  I guess, physical block is the scsi lun 
disk, logical block is lvm disk? right?



With files this is fine as you can seek wherever you want and the file will 
remain sparse.  With block devices this makes little sense as the second the 
guest accesses a block which is mapped to an unallocated physical block we'd 
have to allocate all the area up to that point.
(btw, qemu-img will fail if you try to create such an image on a block device)

Re: [Users] Online snapshot

2012-07-04 Thread Shu Ming
After looking into a qemu a bit,  I believe the snapshot operation on 
the disk in oVirt is not a live snapshot, because the guest VM will be 
paused by qemu when the snapshot is undergoing.That is what qemu 
monitor command snapshot_blkdev does and VDSM depends on that command 
in low level.Most likely,  the pausing time is non-trival for a 
normal snapshot.

That's a system-checkpoint snapshot, because you didn't use --disk-only.
  When you say 'live snapshot' were you intending the fast operation of
just a disk snapshot (via the 'transaction' or 'blockdev-snapshot-sync'
monitor command) or the slow operation of a checkpoint (via the 'savevm'
monitor command)?

This qemu does not support the 'transaction' monitor command, so libvirt
has to fall back to the non-atomic 'blockdev-snapshot-sync', or else
give up because of missing functionality.



dave - who can help us elaborate on this libvirt error:

OK, so this is a case of VDSM driving a different use of the API than
what you did with your virsh command line.  VDSM is attempting to do the
equivalent of 'virsh snapshot-create --disk-only --reuse-ext', but
because your qemu doesn't support the 'transaction' command, libvirt
can't make qemu do what VDSM wants.  Basically, the
'blockdev-snapshot-sync' command in qemu 1.0 lacks the ability to reuse
qcow2 metadata already present in the file pre-created by VDSM; this
wasn't added until the 'transaction' command of qemu 1.1.



ok, i guess the question is then when qemu 1.1 is expected in fedora

[Users] How can I create a snapshot for virtual disks only?

2012-06-27 Thread Shu Ming

Hi,

I am testing oVirt engine 3.1 beta release 06-07.   I tried 
snapshots--create button for a VM and it looked like that the 
snapshot to be created was for both the running state of the system and 
the virtual disks.I am wondering if there is any way to create the 
snapshot only for the virtual disks of the VM in engine?

I understand syncing virtual disk state with the OS cache is a quite 
challenge to a snapshot tool developers.  However, it is a handy feature 
for the users just want to back up their data in the disks without 
stopping VM.  As  other virtualization solution support this feature,  
we should narrow the gap to attract more users to oVirt.

Enhh, interesting.  So it is not live snapshot?   The VM must be paused 
to do the snapshot in my engine.   Also,  I hit a bug to resume the VM 
after the snapshot was done.  The VM was always in pause state after I 
clicked the resume button after the snapshot was done.  I looked into 
the VM by VNC and VNC console showed that the VM was in frozen state.  
Has anyone seen these or has it been fixed in the upstream?





other problem is the VM must be paused when the snapshot is undergoing.

The is no option to save a single disk in webadmin.


live snapshot is for disks only, not for RAM.
so the live snapshot button only snapshots the disks already.


there is a mix of two things here:
1. taking snapshot of a subset of the disks.
2. taking snapshot of disks + ram

1) For read only access,
you can try virsh -c qemu:///system -r
2)For read write access
you can try virsh -c qemu:system,  then input authentication 
name: vdsm@rhevh password: shibboleth

I was trying to use virt-manager on one of the hosts being managed by

libvirt. I get the same thing when I tried to connect via virsh.As I 
understand , VDSM acquires a lock over libvirt. But is it possible to 
connect to libvirt (may be only read-only) ?. What authentication does 
it require ? how do I get the credentials. ?

Subject: [Users] The SPM host  node is in unresponsive mode

Hi,
I attached one host node in my engine.  Because it is the only one
node, it is automatically the SPM node.  And it used to run well in
my
engine.  Yesterday, some errors happened in the network work of the
host
node.  That made the node become unresponsive in the engine.  I am
sure the network errors are fixed and want to bring the node back to
life now.  However, I found that the only one node could not  be
confirm as host been rebooted and could not be set into the
maintenance mode.   The reason  given there is no active host in the
datacenter and SPM can not enter into maintenance mode.  It seems
that
it fell into a logic loop here.  Losting network can be quite common
in
developing environment even in production environment, I think we
should
have a way to address this problem on how to repair a host node
encountering network down for a while.

Hi Shu,

first, for the manual fence to work (confirm host have been rebooted) you 
will need
another host in the cluster which will be used as a proxy and send the actual 
manual fence command.
second, you are absolutely right, loss of network is a common scenario, and we 
should be able
to recover, but lets try to understand why your host remain unresponsive after 
network returned.
please ssh to the host and try the following:

- vdsClient -s 0 getVdsCaps (validity check making sure vdsm service is up and 
running and communicate with its network socket from localhost)
- please ping between host and engine
- please make sure there is no firewall on blocking tcp 54321 (on both host and 
engine)

also, please provide vdsm.log (from the time network issues begun) and 
spm-lock.log (both located on /var/log/vdsm/).

as for a mitigation, we can always manipulate db and set it correctly, but 
first, lets try the above.

I did futher test on this system.  After I killed the solo libivrtd 
process, vdsm processs can be started without libvirtd. However, vdsm 
can not work either in this way. After several round of killall 
libvirtd, service vdsmd start, vdsmd stop,  both  vdsm and 
libivirtd processs now start.  In summary:
1) the libvirtd started by vdsm process may stand there even after its 
parent vdsm process is gone.

2) the legacy libvirtd may block the start process of vdsm service
3) vdsm service can work with the legacy libvirtd sometime without 
creating a new one.


Here are my service process in the host node, please notice that the 
libvirtd process is earlier than the vdsm process that means this 
libvirtd was a legacy process not created by the vdsm process in this round.
The problem still exist in engine that I don't have a way to reactivate 
the host node.

Subject: [Users] The SPM host  node is in unresponsive mode

Hi,
I attached one host node in my engine.  Because it is the only one
node, it is automatically the SPM node.  And it used to run well in
my
engine.  Yesterday, some errors happened in the network work of the
host
node.  That made the node become unresponsive in the engine.  I am
sure the network errors are fixed and want to bring the node back to
life now.  However, I found that the only one node could not  be
confirm as host been rebooted and could not be set into the
maintenance mode.   The reason  given there is no active host in the
datacenter and SPM can not enter into maintenance mode.  It seems
that
it fell into a logic loop here.  Losting network can be quite common
in
developing environment even in production environment, I think we
should
have a way to address this problem on how to repair a host node
encountering network down for a while.

Hi Shu,

first, for the manual fence to work (confirm host have been rebooted) you 
will need
another host in the cluster which will be used as a proxy and send the actual 
manual fence command.
second, you are absolutely right, loss of network is a common scenario, and we 
should be able
to recover, but lets try to understand why your host remain unresponsive after 
network returned.
please ssh to the host and try the following:

- vdsClient -s 0 getVdsCaps (validity check making sure vdsm service is up and 
running and communicate with its network socket from localhost)

[root@ovirt-node1 ~]# vdsClient -s 0 getVdsCaps
Connection to 9.181.129.110:54321 refused
[root@ovirt-node1 ~]#

root@ovirt-node1 ~]# ps -ef |grep vdsm
root  1365 1  0 09:37 ?00:00:00 /usr/sbin/libvirtd 
--listen # by vdsm

root  5534  4652  0 13:53 pts/000:00:00 grep --color=auto vdsm

--listen # by vdsm

root  5534  4652  0 13:53 pts/000:00:00 grep --color=auto vdsm

It seems that VDSM process was gone while libvirtd spawned by VDSM was 
there.  Then I tried to start the VDSM daemon, however it did nothing.  
After checking the vdsm.log file, the latest message was five hours ago 
and useless.  Also, there was no useful message in libvirtd.log.




- please ping between host and engine

 It works in both ways.



- please make sure there is no firewall on blocking tcp 54321 (on both host and 
engine)


No firewall.



also, please provide vdsm.log (from the time network issues begun) and 
spm-lock.log (both located on /var/log/vdsm/).

as for a mitigation, we can always manipulate db and set it correctly, but 
first, lets try the above.
Also, there is no useful message in spm-lock.log.  The latest message 
was 24 hours ago.

not yet.
engine only deals today with mac address pools, which you can use dhcp 
to assign.


If we don't have such features today,  I would like to initiate a new 
project page about this.  The basic idea is:
I) Engine should have a pool of IPs. Engine also can assign a specific 
IP to the VM or assign a random IP in the pool to the VM
II) ovirt agent in guest should request the IP from VDSM. And VDSM proxy 
its request to engine.

III)After ovirt agent get the IP, it can configure the system in one time.

Hi everyone,

I am new to ovirt and can't find any documentation about how to import

a template because I plan to create other virtual machines based off 
this VM.


I tried virt-v2v, but it will only work if I have a datacenter setup 
with NFS. In my case, I have a datacenter setup for local storage hosts.


Don's know where are your datacenters.  If both of your datacenters are 
managed by oVirt,  You can export the existing VM in datacenter.  And 
then let the other datacenter to import it.

Is it a master data domain? Does you mean you can not remove the data

The docs clearly state that the OVirt Engine must run on a box that
is
fully DNSed, both forward and backward. I've done that but am having
trouble connecting a Node box that is not DNSed but does have a
static
IP. Do I need to DNS the Node box as well?

As per Itamar's response this relates to an issue with the version of libvirt 
that we originally released on, as I understand it even where this applies 
though not having an FQDN for the node(s) only impacts migration. Not being 
able to connect the node at all sounds like a different issue.

I can mount the  xxx.xxx.xxx.110:/data by mount -t nfs 
xxx.xxx.xxx.110:/data /mnt manually in the ovirt-engine host, also a 
new file can be created under the mounted directory with touch xx.  
It looks to me that there is no permission problem when I access the 
remote nfs path manually.  So does ovirt-engine enforce additional 
permission check beside the normal unix file permission check here?

Re: [Users] permission settings on the specified path do not allow access to the storage

2012-03-06 Thread Shu Ming
The problem was resloved  and It might come from the naming problem 
using 'data' as domain name.

It seems that the problem came from the name of the data domain to be
created.  I used data to be the name.  Is data a reserved name for the
storage domain?

Subject: [Users] Network configuration


I feel like I have been bombarding this list the last few days,
sorry!
I have been looking at the different possible network configurations
shown at http://www.ovirt.org/wiki/Vdsm_Network and trying to work
out how to achieve the second topology ( bridge over vlan over nic
). I can see that it is possible to assign a logical network to a
physical network on a node but how can you add more than one as this
is a dropdown menu? My nodes have two NICs, one of these is for the
management network but I could like to have a number of logical
networks (with different VLAN tags) connected to the other NIC.
Is this currently possible using the web UI?

Very simple
1. create your logical networks with vlan tags in the data centre
2. assign those networks to the relevant cluster

Now, assuming we are going to assign network X with tag 100 and network Y with 
tag 200 to eth0 on a host:
Edit eth0 on the host - assign network X to it
see how eth0.100 gets created and the X network attached ot that tagged 
interface
Edit eth0 again, assign network Y
see how eth0.200 gets created and Y is attached

repead for additional tagged networks


Yes, we can do these manually if we are the master of the system 
administrator.  But I think we should provide a UI to the user and VDSM 
management API in the backend.  Also, it is a quite a challenge to 
assign the VMs in different host to the same vlan.

I have tried using ovirt-setup again, but that does not help. I also 
have tried: engine-config -l AdminPassword=password


Have you tried engine-cleanup before engine-setup?

Re: [Users] Ovirt Engine as a VM

2012-02-19 Thread Shu Ming

Had anyone created a how to or notes on how to manage an ovirt engine 
as a guest on the cluster? This should be possible, when the cluster 
is powered up for the first time it would require some specialized 
instructions to fire up the ovirt engine on a node.


Does the guest(VM)  hosting the ovirt-engine be managed by the 
ovirt-engine?  If It does,  it looks like a logical loop here.  Say,  if 
the ovirt-engine stop the hosting VM,  the ovirt-engine will also be 
stopped.




P.S. Are there any plans for redundant ovirt engines in the works?
